I've only had experiences with a Kahr PM9 - let's just say there were some serious issues with that gun hitting over 2 feet from point of aim and a few other things on it out of the factory (not saying all Kahrs are bad at all here).
The PM series lets the slide ride on the polymer frame, ala Ruger series without any inserts from what I can tell. I've seen plenty of frames being chewed up and having shavings and whatnot all over the place in the PM9 series especially.
From what I can see, the P series has two steel inserts in the rear of the frame, but doesn't have any up front. Shouldn't be a big deal. Anybody here have any experiences on a P series of any caliber with a round count of over 300? I've seen plenty of PM series postings here, but about zero on the P series.
I may/may not have the opportunity to purchase a Kahr P45 at a decent price from somebody who's stubborn and won't listen to anybody out there. I told him after a field strip and pictures of all the parts, and assuming the warranty hasn't been registered yet, I might snag it.
